On 14 January 2016, 60-year-old businesswoman Sadie Hartley was brutally murdered in her Lancashire home in a shocking and premeditated attack. Stunned with a cattle prod and stabbed more than 40 times, her death was described by the judge as “not a crime of passion, but a crime of obsession, arrogance, barbarity, and pure evil.” The investigation quickly uncovered a calculated plan by Sarah Williams and her accomplice Katrina “Kit” Walsh, who had stalked Sadie for months using GPS trackers and CCTV. Walsh’s diary detailed their disturbing obsession and planning, leading detectives straight to them. In August 2016, Williams was sentenced to a minimum of 30 years in prison, and Walsh to 25. The murder of Sadie Hartley shocked the UK and remains one of the most disturbing cases of jealousy and revenge ever recorded, a chilling reminder of how obsession can spiral into pure evil. 🔴 Try my Classified Coffee! - https://bit.ly/3PrY9CS ➤ Patreon: https://www.patreon.com/coffeehousecrime ➤ Instagram: https://www.instagram.com/coffeehousecrime/ ➤ Twitter: https://twitter.com/coffeehcrime ➤ Facebook: https://www.facebook.com/coffeehousecrime ➤ Animated Background by Featherwax Studio: https://featherwax.com DISCLAIMER: Great effort is made to ensure all materials in Coffeehouse Crime's videos fall within the guidelines of fair use.
